Running RapidMiner Model from my IDE

Hi All,
There is a model I've developed in RapidMiner. The model's results sensitive to several parameters.
I'd like to run this model and record the result where the parameters are the arguments.
Running it manually is very tedious and time consuming.
I was wondering if there's a way of running it from and external program, either C++ or Java.

Thanks a lot in advance,
Omer

    Hi,

    if I understood you correctly, you can use a normal RapidMiner process for that. Just change the model parameters from fixed values to macros. You can then for example run the RM process via java and change the macros each time.
    To set a macro as a parameter, just enter 

    %{macroName}
    as a parameter value.

    See here for instructions on how to run a RM process via java.

    To change macro values, you can do this: 

    MacroHandler handler = operator.getProcess().getMacroHandler();
    handler.addMacro("macroName", "newValue");
    Regards,
    Marco
